Kev Piav Qhia & Nta

Piav Qhia: WNX siv cov thev naus laus zis tsim khoom tsis siv neeg thiab siv cov khoom siv raw zoo los tsim cov khoom zooCeric Sulfate.

Cov Nta Tseem Ceeb:

Kev Ntshiab Siab:Ceric Sulfate tsis muaj cov khoom tsis huv los ntawm cov khoom tsis tshua muaj (xws li hlau, calcium, sodium), thiab cov ntsiab lus tsis huv yog tsawg.

Kev yaj zoo:Ceric Sulfate tuaj yeem yaj sai sai hauv dej thiab cov kua qaub muaj zog.

Kev sib xws: Kev tswj hwm cov khoom nruj hauv kev tsim khoomCeric Sulfate ua kom ruaj khov zoo rau kev lag luam loj.

Cov tshuaj catalyst rau kev lag luam tshuaj lom neeg: Sulfuric acid siab cerium, ua ib qho oxidant muaj zog, yog siv rau hauv cov organic synthesis los catalyze ntau yam kev tshuag, suav nrog kev xaiv oxidation ntawm cov cawv rau ketones, qhov ncaj qha sulfonation ntawm methane thiab trioxide sulfur los tsim methanesulfonic acid, thiab catalysis ntawm condensation ntawm 2-naphthol nrog aldehydes nyob rau hauv cov xwm txheej tsis muaj kuab tshuaj thiab microwave los ua 14-aryl lossis 14-alkyl-14H-dibenz [a, j] sulfuranthene. Nws cov khoom oxidizing yog qhov tseem ceeb tshwj xeeb nyob rau hauv cov xwm txheej acidic.

Tshuaj Tshem Tawm Phosphorus Hauv Pas Dej: Vim nws cov khoom siv tshuaj lom neeg, sulfuric acid high cerium tuaj yeem tshem tawm cov phosphate ntawm cov dej los ntawm kev nag, uas yog qhov pab tau rau kev daws teeb meem ntawm cov dej eutrophication.

Cov roj teeb thiab cov khoom siv zog: Sulfuric acid nrog cov ntsiab lus cerium siab yog siv ua cov khoom ua ntej rau kev npaj cerium oxide (CeO₂) nanospheres. Cov nanomaterials no ua rau pom kev ua tau zoo heev hauv kev txo cov tshuaj nitric oxide (NO) thiab muaj peev xwm siv tau hauv kev siv hluav taws xob thiab kev ua kom ib puag ncig zoo.

Cov tshuaj lom neeg nruab nrab: Sulfuric acid cerium (IV) yog ib qho tshuaj tseem ceeb rau kev tshuaj ntsuam xyuas, siv dav hauv kev ntsuas oxidation-reduction titrations (xws li calibrating sodium thiosulfate solutions) los txiav txim siab cov tshuaj uas tuaj yeem oxidized, xws li nitrite, iodide, thiab cov ntsev hlau qis-valent. Nws kuj yog ib qho tseem ceeb nruab nrab rau kev tsim lwm cov tshuaj cerium (xws li cerium dioxide).
